IMPROVEMENT IN APPARATUS FOR MAKING PAPER COLLARS.A

Specification forming part of Letters PatentNo. 43,870, dated August 16,1864.

To all whom it may con/cern:

Be it known that l, DAVID M. SMYTH, of the city, county, and State of New York, have invented certain new and useful Improvementsin Machineryfor Making Iaper Gollars 5 and I do hereby declare that the following isa full, clear, and exact description thereof, reference being had to theaccompanying drawings, making part of this specifi cation, in which-Figure 1 is afront elevation Fig. 2, a cross vertical section; Fig. 3, aface View of the lower press face or die and the opening through whichthe collars are dischargedv when cut, and Fig. 4 a face view of theupper press-face and the punch by which the colars are punched or cut.

The same letters indicate like parts in all the figures.

By my taid invention the edges of the collar are so cut as to present abetter edge than by any other means heretofore employed for the purpose.The surface near the edge is embossed in imitation of stitching, and theparts are so combined that as one collar is being cut off, the surfaceof the paper is being embossed and the holes for the buttons punched foranother collar. The collars are cut successively from a long sheet ofpaper, which is a little wider than the length of the collars to bemade.

In the accompanying drawings, a represents a suitable frame, and b thebed, which forms the lower press face or die, c, and what may be termedthe female 7 portion of the shears. rIhe lower die, c, is simply a flat,smooth face of metal. I prefer to make it of steel. There are threeapertures, d d d, made in it of the form of the button-holes required tobe made in each collar. These holes should be formed with sharp, squareedges; and for the purpose of embossing the surface a short distancewithin the upper edge in imitation of the stitching, two line wires aretwisted together and secured in a groove, as at c, the groove being madeof such depth as to leave a sufficient portion ofthe diameter of thetwisted wires projecting above the surface of the bed or die c.

Heretofore the imitation of stitching hasbeen. very imperfectly done byfine teeth cut in the edges of two thin plates inserted in the bed ordie, which simply emboss two rows of of the collar when completed.

pointed indentations, notat all representing stitches 5 but by my saidimprovement, which consists, in this, respect, in substituting two wirestwisted together, the embossing produced therebyT resembles veryaccurately the two rows of stitches. The twisted wires are to be placedto suit the shape of the collar to be made, so that the rows of stitchesshall be at the required distance within the edge A mortise, j', of thesize and shape of the intended collar is formed through the bed o,leaving the'upper edge square and sharp, andthis forms what I term thefemale 7 part of the shears. .lo this mortise is accurately fitted aplunger, g, which forms the male portion of the shears. This is securedto the Linder face of a follower, z, which is fitted to slide insuitable ways, t' t', of the frame, so as to slide accurately therein;and the lower face of this plunger g is beveled in opposite directionsfrom the middle toward cach end, so as to give the cutting-ed gesthereof, in entering the mortise'or female [art of the shears, ashearing eut, so that by this and the accuracy with which which it fitsthe mortise the collars will be cut with a perfectly smooth edge, andwithout bending the paper, thereby avoiding a serious difficultyheretofore experienced. rIhe face of the follower h'by the side of theplunger should be smooth and parallel with the fa'ce of the die or bedc, and this is provided with three punches, d d d', so as to accuratelyfit in the apertures cl d d in the bed, to punch the button-holes. Thefollower receives an up-anddown motion from an eccentric, j, on ahorizontal shaft, 7c or the required motion may be given by other andequivalent means. While the follower is up, the sheet of paper is pushedin by hand until its forward edge strikes two gage-stops, I l, on thebed c, and as the follower descends, a 'collar is cut or punched fromthe sheet and discharged through the mortise or female portion of theshears, while by the same operation the sheet of paper beyond is punchedto form the button-holes, and the surface is embossed ready to be cut orpunched by the next operation to complete another collar. In this way itwill be seen that at each operation a collarl is completed anddischarged.

What I claim as my invention, and desire to secure by Letters Patent, is
